％ 采用数字分段匹配的方式，将数字分为横、竖、左半弧、右半弧、上半弧、下半弧、
％ S、反S、环 共9种元素，数字的元素间按照上、下、左、右、中5种相对关系进行定义。
％ 此时不采用绝对位置，而用相对关系的位置更具有鲁棒性，这样一共是45个维度。- Using digital sub-matching methods, the number is divided into horizontal, vertical, the left arc, right arc, arc the first half, second half of arc, S, anti-S, ring a total of nine kinds of elements, the number of elements in accordance with the upper and lower, left, right, in the relative relationship between the five kinds of definition. At this time do not use absolute position, and relative position with a more robust, so that a total of 45 dimensions.
